Subwoofer Amps | High Pass Filters
I have just built a ported sub woofer & can't seem to get any frequency below 30 hz.
The sub woofer driver is a Mach audio IXL 18.
The cabinet was designed with the help of gperkins_1973 & is tuned to 15hz.
There is a build thread (I tried to insert the link but became to long)
